IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent-No. 196,622, dated October 30, 1877; application filed August 7, 1877.

To all whom 'it may concern:

Be it knownthat I, LEwIs T.'BEAvER, of Placerville, in the county of El Dorado and State of California, have invented a new and useful Improvement in Car-Couplings, which improvement is fully set forth and described in the following speciiicat'ion and accompany- "9J-.drawing automatic car-coupling combining strength with simplicity of construction and ease of operation.

It' consists in a bumper-head having a recessed chamber, in which is pivoted an eccentric, and provided-with a pin-hole in its upper front portion, and a horn on the eccentric pro- .jecting over this portion of the bumper, and

I having a pin-hole coincident with the rstmentioned pin-hole, as fully hereinafter eX- plained.

A represents the draw-head or bumper; B,

l the recess or chamber; C, the locking-tumbler;

D, its pivot; and E, the coupling-bar, with a barbedhead.

The eccentric C has an eye or ring, a, to which a cord or rod is secured for raising the eccentric when unooupling the cars.

The chamberB is of such form thatthe barbed head of the link` is held by the eccentric-tumpin of ordinary form can be inserted when a car having the ordinary style of draw-head is to be connected with a car having my coupling applied to it.

The eccentric-tumbler keeps its position by its own gravity, and when the end ofthe coupling-bar, in entering the chamber, pushes it back, it drops in front of the barbed head of the pin, and locks automatically upon it. The upper horn c of the tumbler projects over the top of the draw-head, and regulates the extent of the upward motion. Through this horn c is formed a hole, b', coincident with the pinhole b in the bumper-head; and in using the ordinary link the coupling-pin is passed down through both of the holes b b,which holds the eccentric C in the head, and prevents it from rattling or working loose.

The coupling-bar E is employed in connection with my invention when a car having a draw-head of the kind using an ordinary pin is to be coupled to a car with my draw-head and coupling. It is provided with a barbed head at one end, and a slot or link at the other, as shown in the detail view, Fig. 4.

Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

The combination, with the bumper-head A, having the recessed chamber B and provided with pin-hole b, of the eccentric C, pivoted in said chamber, and having a horn, c, projecting over the top of the bumper-head, and provided with a pin-hole, b', coincident with the hole b, constructed and arranged substantially as described and shown.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 19th day of June, 1877.
